Abstract
An antiperspirant composition buffered to a pH in the range of from about 2.5 to about 4.5 having incorporated therein as active ingredients a combination of aluminum chlorohydrate, aluminum chloride and an aluminum zirconium polychlorohydrate complex; an additionally added buffering agent, preferably glycine, may be incorporated in the composition.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. An antiperspirant composition buffered to a pH in the range of from about 2.5 to about 4.5, said composition containing as active ingredients, on an anhydrous basis: (1) from about 1.5% to about 3.3% aluminum chloride, (2) from about 2% to about 10% aluminum chlorohydrate, (3) from about 8% to about 14% of an aluminum zirconium polychlorohydrate complex, and (4) from about 1.5% to about 3% glycine, the balance of the composition containing a suitable quantity of at least one carrier, all percentages being weight percentages based on total anhydrous composition weight.
2. The composition of claim 1 containing about 1.7% aluminum chloride, about 7.2% aluminum chlorohydrate, about 9.1% aluminum zirconium tetrachlorohydrate-glycine, and about 0.50% glycine.
3. The composition of claim 2 wherein the carrier is aqueous and the composition also contains about 2.25% polypropylene glycol(11)stearyl ether, about 1.65% polyoxyethylene(2)stearyl ether and about 0.6% polyoxyethylene(20)stearyl ether.
4. The composition of claim 3 which also contains about 0.1% disodium edetate dihydrate.
5. The composition of any one of claim 1-4 in the form of an emulsion comprising a water phase wherein the active ingredients are in said water phase.
6. The composition of claim 1 containing about 2.2% aluminum chloride, about 4.0% aluminum chlorohydrate, about 11.75% aluminum zirconium tetrachlorohydrate-glycine and about 0.50% glycine.
7. The composition of claim 6 wherein the carrier is an aqueous carrier and the composition also contains about 2.25% polypropylene glycol(11)stearyl ether, about 1.65% polyoxyethylene(2)stearyl ether.
8. The composition of claim 7 which also contains about 0.1% disodium edetate dihydrate.
9. The composition of any of claims 6 through 8 in the form of an emulsion comprising a water phase, wherein the active ingredients are in said water phase.
10. An antiperspirant composition buffered to a pH in the range of from about 2.8 to about 3.8, said composition containing as active ingredients, on an anhydrous basis: (1) from about 1.7% to about 2.2% aluminum chloride, (2) from about 4% to about 7.2% aluminum chlorohydrate, (3) from about 9.1% to about 11.75% of an aluminum zirconium polychlorohydrate complex, and (4) about 1.5 to about 3% glycine, the balance of the composition containing a suitable quantity of at least one carrier, all percentages being weight percentages based on total anhydrous composition weight.
11. The composition of claims 1 or 9 wherein the aluminum zirconium polychlorohydrate complex is selected from the group consisting of: aluminum zirconium tetrachlorohyrate; aluminum zirconium tetrachlorohydrate glycine; aluminum zirconium trichlorohydrate; aluminum zirconium trichlorohydrate glycine; aluminum zirconium pentachlorohydrate; aluminum zirconium pentachlorohydrate glycine; aluminum zirconium octachlorohydrate; aluminum zirconium octachlorohydrate glycine; and mixtures thereof.
12. A method of inhibiting perspiration in a subject which comprises applying to the skin of said subject an effective amount of the composition of any one of claims 1-11.Join the waitlist — get patent alerts
